Inverting and cleaning device

Abstract

An inverting and cleaning device includes a positioning mechanism, an inverting mechanism, and a cleaning mechanism. The positioning mechanism is adapted to move a drum to a first position. The inverting mechanism includes a holding member. When the drum is located at the first position, the holding member clamps a drum body of the drum and inverts the drum to a second position where an opening on a top of the drum faces downward. The cleaning mechanism includes a cleaning tool. When the drum is located at the second position, the cleaning tool enters the drum through the opening of the drum for cleaning an inside of the drum.

What is claimed is: 
     
       1. An inverting and cleaning device, comprising:
 a positioning mechanism adapted to move a drum to a first position; 
 an inverting mechanism comprising a holding member, wherein when the drum is located at the first position, the holding member clamps a drum body of the drum and inverts the drum to a second position where an opening on a top of the drum faces downward; and 
 a cleaning mechanism comprising a cleaning tool, wherein when the drum is located at the second position, the cleaning tool enters the drum through the opening for cleaning an inside of the drum; 
 wherein the positioning mechanism comprises a conveyor belt, a positioning frame, a first roller, and a second roller; the conveyor belt is adapted to convey the drum; the first roller is disposed on the positioning frame; the positioning frame and the second roller are respectively disposed on two lateral sides of the conveyor belt; the positioning frame is controllable to pivot between a third position and a fourth position; when the positioning frame is located at the third position, the first roller is not in contact with the drum; when the positioning frame is located at the fourth position, the first roller is in contact with a side of the drum to make another side of the drum be in contact with the second roller; the second roller is driven by a driving member to spin to drive the drum to turn around an axis. 
 
     
     
       2. The inverting and cleaning device as claimed in  claim 1 , wherein the positioning mechanism comprises a controller and a sensor; the controller is electrically connected to the driving member and the sensor; the sensor is disposed on the positioning frame; when the positioning frame is located at the fourth position, the sensor is located on the top of the drum and is adapted to detect a position of the opening of the drum during a turning process of the drum; when the sensor detects that the opening of the drum is located at a predetermined position, the controller stops the operation of the driving member to hold the drum in the first position. 
     
     
       3. The inverting and cleaning device as claimed in  claim 1 , wherein the holding member clamps the drum body of the drum and inverts the drum by 180 degrees from the first position to the second position. 
     
     
       4. The inverting and cleaning device as claimed in  claim 1 , wherein the cleaning mechanism comprises a lifting driving member; when the drum is located at the second position, the cleaning tool and the opening of the drum are both located on a vertical axis; the cleaning tool is driven by the lifting driving member to move up and down along the vertical axis. 
     
     
       5. The inverting and cleaning device as claimed in  claim 4 , wherein the cleaning tool comprises a liquid spray head and a gas spray head. 
     
     
       6. The inverting and cleaning device as claimed in  claim 1 , wherein the inverting mechanism comprises a support; the holding member comprises two holding arms, two clamping members, and two cylinders; an end of each of the holding arms is connected to the support; each of the cylinders is disposed on another end of one of the holding arms; each of the clamping members is connected to one of the cylinders; the clamping members are driven by the cylinders to change a distance between the clamping members. 
     
     
       7. The inverting and cleaning device as claimed in  claim 6 , wherein the inverting mechanism comprises a driving motor; the holding arms are driven by the driving motor to pivot relative to the support. 
     
     
       8. The inverting and cleaning device as claimed in  claim 1 , further comprising a lifting mechanism connected to the inverting mechanism, wherein the lifting mechanism is adapted to drive the inverting mechanism to move up and down; when the drum is located at the second position, the lifting mechanism drives the inverting mechanism to move downward to make the cleaning tool enter the drum through the opening of the drum.
